Question

If straight hair is dominant to curly hair, what genotype would you expect to see if the phenotype is curly?

Answer 1

Answer:

B: ss

Explanation:

Since straight hair is dominant it would be a capital S and curly would be a lower case s. If a straight hair gene was in the genotype it would block out the curly hair, so the only way to have curly hair would be ss.

Answer 2

Answer:

B: ss

Explanation:

In order for the recessive curly-haired gene (s) to be expressed in the phenotype, there needs to be no dominant straight haired gene (S) in the genotype.
